Ithink aluminum arrows would be fine, I guess.
For your first round of arrows, I would use aluminums. I still use them except for the occasional wood arrow. Maybe get some new gamegetters. Chances are you will be missing the target on occasion when starting out. I know that I don't feel as bad when I miss with $5 arrow compared to a $20 arrow. Heck thats one of the reasons that I sold my carbon Grizzly Sticks, I wastoo afraid of missing - still. [:@]
If you do miss with the gamegetter, check for any fractures and spin them, even with a little wobble, I'd still use them when starting out.
